Hot days, warm evenings and a rain trade-off

Expect summer warmth rather than mild sightseeing weather. Compared with London's December daytime average of 8°C, Mauritius feels like a substantial change, and lightweight clothing makes sense throughout the day. Average sunshine of 6.5 hours leaves scope for time outdoors, but the rainy-day figure means you should not build the whole trip around clear skies. Keep plans flexible and carry rain protection rather than assuming every day will suit the beach. At midday, favour shade and take breaks from the heat. Nights average 24°C, so evenings remain warm rather than offering much of a cool-down. This suits travellers comfortable with warmth after dark.

Flic en Flac or Belle Mare?

Flic en Flac gets the nod if your main aim is to reduce the chance of rain disrupting outdoor plans. It averages 12 rainy days, compared with 19 in Belle Mare, so the difference in rainfall frequency matters more than the small temperature gap. Flic en Flac reaches 29°C by day, while Belle Mare averages 28°C: neither is a cool-weather option. Both have nights of 24°C and sea temperatures of 27°C, so choosing Belle Mare does not buy you cooler evenings or a different swimming temperature. Choose Flic en Flac for the drier balance, and Belle Mare if slightly lower daytime heat matters more.
